Ecological controls on geometries of carbonate platforms: Miocene/Pliocene shallow-water microfaunas and carbonate biofacies from the Queensland Plateau (NE Australia)

The sensitivity of ECHAM4/ML to a double CO2 scenario for the Late Miocene and the comparison to terrestrial proxy data

“…Thus, in tropical and subtropical latitudes the discrepancies between the 2×CO 2 Tortonian run and proxy data are increased as compared to the Standard Tortonian run. For the Southern Hemisphere during the Miocene, investigations on tropical reef growth rates in the north-east of Australia indicate water temperatures close to 20°C (Isern et al, 1996;Betzler, 1997). This is not reproduced by any of our simulations.…”

“…Finally, we add some qualitative climate information from studies of Bertini (1994), Isern et al (1996), Betzler (1997), Markwick (1998), van Dam and Weltje (1999), and Alonzo-Zarza and Calvo (2000). For the Miocene, the data base is quite poor for most parts of the world (Mosbrugger and Schilling, 1992).…”

Seismic geomorphology and growth architecture of a Miocene barrier reef, Browse Basin, NW-Australia

“…Carbonate platforms play a special role within the sedimentary systems as they are able to produce their own sediments. They react dynamically to a variety of ecologic controlling factors (temperature, light, current/wave energy, substrate) and through them indirectly to climatic, tectonic and ocenanographic changes (Schlager, 1989;Betzler, 1997;Reuning et al, 2006a). These factors control type, amount and distribution of the produced carbonate sediment.…”

Evolution and Geological Significance of Larger Benthic Foraminifera

“…The change from biconvexity to biclavate morphology in axial section retained the development of massive pillars, which ultimately became thinner in species such as L. (N.) ferreroi (Pate 7.17,. All Lepidocyclinidae disappear completely towards the end of the Early Miocene in the American province (BouDagher-Fadel and Price, 2010a) and in the southeastern Tethys in the Late Miocene (Hallock and others, 2006;BouDagher-Fadel and Price, 2013) or possibly in the Early Pliocene (Betzler, 1997) (see Fig. 7.18).…”

“…They reportedly went extinct in the middle Miocene (Serravallian) in Indonesia and the northern Indo-Pacific (BouDagher-Fadel and Price, 2010a), but extended into the late Miocene (Tortonian) off Australia (Hallock and others, 2006). Reports of early Pliocene occurrences off Australia and the Pacific islands (Betzler, 1997;Adams et al, 1979) might represent reworked material and requires further biostratigraphic study to confirm their age (BouDagher-Fadel and Price, 2010a).…”
